v*a=w

so ? * 628 = 1,000,000

you do the math part, I'm lazy

Me too, that's why I want it in the article.

Ah is not a good unit for explaining capacity, it's better to use Joules. Ah is better suited to throughput because it informs the maximal load that can be applied.

Agreed Ah are bad.

MWh are equivalent to J. Specifically 1MWh is 3.6GJ

Those look like Retro Encabulators

Big cells aren't necessarily good... if something goes wrong that's a lot of energy being impacted. If a cell goes bad, that's a more expensive repair. I'm sure there's other issues as well.

It can save on initial costs though in various ways as well.

There's going to be some equilibrium where size, cost, safety all converge
